spring 39 on this rod presses the end of the arm 33 up or,down while permitting it to swing across the lineI between the pin 36 and shaft 28, to hold the plate 30 in depressed or elevated positions. Brackets 40 project from the opposite pedestal and carry a shaft 41,

' on which is mounted a lever 42 whose lower apart by the material between them, is controlled by the screws 48.'

Many changes may be made in the details of construction without departing from the spirit of this invention.

'what I c aim as in The operation of the machine is as fol, lows: The apron 21 havingbeen properly adjusted and secured, the operator lifts the front end of the lever 32, thus starting the machine. The spring 39 holds up the lever 32 and also holds the clutch-sleeve 8 in engagement with the pulley 6. If the revers ing mechanism is not employed, the machinewill continue in motion in the same direction. W'here the reversing mechanism is employedthe sheet will engage the plate 30 at the proper time and swing down the arm 46, sli ing the sleeve withthe pulley 6 and into engagement with the pulley 7'. The arm BB will be swung down from 36 and shaft 28 to lbelow it, where held by the spring Havin now explained my improvements, invention and desire to secure' by Letters atent is 1. In a bending-machine for ribbed sheetmetal, the combination of a lower roll having grooves to receive the ribs. on the sheet-l metal, an upper roll having rings to enter it will be .the grooves, a plate to support the sheets as they are fed between the rolls,` and an adjustable grooved plate to engage the sheets as they emerge from the rolls, and means to adjustably sup ort said plate.

2. In a ben ing-machine for sheet-metal, the combination of a table, rolls mounted on said table, brackets extendi upward from the table, an apron mounte between said brackets adjacent said rolls to engage the sheet metal as it leaves the rolls, and an adjusting screw indented inV said table to en- B out of engagement-v above the line between the pin `sheets as they are' gage the apron to control the inclination of the same.

3. In a bending-machine for,` ribbed sheetmetal, the combination of a lower roll havto receive the ribs on the sheet ing rooves meta an upper roll having rings to enter the grooves, a grooved stationary late to support the sheets as they are fed etween the rolls, and an adjustable grooved plate to en age the sheets as they emerge from the ro ls. i

4. In a bending-machine for sheet-metal, the combination of a frame, bending rolls mounted thereon, a reversible driving mech anism for the rolls, a lever to control the drivingr mechanism, means to support the sheet metal as itcomes'from therolls, and means in the path of the Vsheet-metal and adapted to be shifted by the same for actuating the cont-rolling lever to reverse ythe rolls.I

5. In a bending-machine for sheet-metal, the combination of a frame, rolls mounted thereon, a reversible driving mechanism for the rolls, means to support the sheet metal as it comes from the rolls, and means adapted Yto be shifted by the sheet-metal as it passes through the rolls for reversing the driving mechanism.

(i.Av In a bending-machine 4for Vsheet-metal, the combination of a frame, bending rolls mounted thereon, mechanism for driving the rolls inv either direction, a vertical reversing lever having a cam'at its upper end, ashaft mounted on the frame having an arm in the path of the sheet-metaland adapted to be oscillated by the same as it 4passes through the rolls, a second arm connected thereto and in engagement with the cam-endY of the reversing lever, and means to hold said arms at either end of their movement.

7. In a bending-machine for sheet-metal, the combinationfof a frame, a pair'of rolls mounted thereon, a plate to support the fed to the rolls, an apron mounted on saidfframe to engage v"the sheets as they emerge from between the rolls, and a screw mounted on the frame and engaging the apron to adjust the inclination of .the same'with reference to said plate and thereby control the curvature of the metal sheets.
